You do a lot of photography with your smartphone, but do you know the difference between OIS and EIS?
When shopping for a smartphone, you've likely heard terms like OIS and EIS. These technologies are now being used in many smartphones. But do you know what they mean? Both have their own advantages and limitations. Before buying a phone, understand which technology might be best for you.
Camera quality in today's smartphones depends not only on megapixels, but also on stabilization technology. Companies are offering technologies like OIS and EIS to ensure shake-free photos and videos.
Many people engage in mobile photography extensively, but don't understand the real difference between these two technologies. If you're interested in knowing which technology is best for you, here's the full details.
What is OIS and how does it work?
OIS, or Optical Image Stabilization, is a hardware-based technology in which the camera lens or sensor automatically moves to counteract vibrations. OIS controls movement in real time, even when the phone is shaken or shooting in motion.
This translates to clearer and sharper images even in low light. OIS also provides a natural and smooth output for video recording, as it doesn't reduce quality during processing.
What is EIS and how does it work?
EIS, or Electronic Image Stabilization, is entirely software-based. The system digitally stabilizes the frame by cropping the footage. While this technology helps videos appear shake-free, quality can sometimes suffer.
Especially in fast-paced motion or low-light situations, EIS isn't as accurate. However, the advantage of EIS is that it can be added to phones at a low cost, making it common in budget smartphones.
Key Differences Between OIS and EIS
OIS is a hardware technology, while EIS is software-based. OIS is more beneficial in low light conditions because it stabilizes the actual frame.
EIS, on the other hand, uses digital adjustments, so image quality may be slightly reduced due to frame cropping and processing.
Both technologies are useful for video stabilization, but OIS produces a more natural output, while EIS can sometimes exhibit a jelly effect during fast movements.
Which technology is better for whom?
If you do a lot of low-light photography, night mode shooting, travel videos, or recording while walking, OIS is a better and more reliable technology for you.
However, if you're using a budget phone and only create social media Reels or casual videos, EIS can also work well. Many brands are now offering hybrid stabilization, combining both technologies, to give users a smoother and more professional output.
